Polypropylene
Lightweight, chemically resistant and heat-tolerant — and the one material where a single supplier makes the print sheet, the printer and the filament. The complete, validated PP workflow, from one place.
Sheet, printer, material — fully integrated
Polypropylene is notoriously hard to stick to a print bed. Most workflows stitch together tape, third-party filament and a machine that was never tuned for any of it. Prusa makes all three parts — the dedicated PP print sheet, the printer and the filament — so the surface, the profile and the material are validated to work together.



Prusament PP
In-house PP and PP composites (Glass Fiber, Carbon Fiber) to a guaranteed diameter tolerance — lightweight, chemically resistant, heat-tolerant.

Polypropylene resists a wide range of solvents, non-oxidized bases, acids and oils — the kind of chemical exposure that degrades most printable plastics. It’s lightweight, and its low moisture uptake means drying isn’t necessary before printing.
The fiber-filled grades add dimensional stability: PP Glass Fiber resists heat up to 138 °C and prints large parts with little to no warping, even without an enclosure. PP Carbon Fiber offers a matte finish and heat resistance up to 120 °C. Both need a hardened nozzle, as the fibers are abrasive.
The trade-off is lower layer-to-layer adhesion than pure PP — something to design around, and something our team can advise on.

Industries & applications
Prusa’s own examples center on the lab and the chemical bench — exactly where PP’s resistance earns its keep.

Lab & medical-adjacent
Vial stands, custom racks and heat- and chemical-resistant labware — Prusa’s cited use for PP. Low moisture uptake suits humid and wash-down environments.

Chemical handling
Chemically resistant canisters and lids, chlorine-pool dispensers and replacement parts that live in contact with solvents, acids and bases.

Packaging & fixtures
Lightweight, tough functional parts, jigs and fixtures — and automotive / RC components where PP’s chemical and heat resistance matter.
Light enough to fly, tough enough to work
Prusament PP is a genuinely lightweight polymer — its technical data sheet lists a density of just 0.91 g/cm³ (ISO 1183). Prusa notes that PP’s lightweight properties make it suitable for the aerospace industry, as well as for hobby RC aircraft — the same weight-to-strength logic that matters on a UAV airframe.
Add PP’s very good chemical resistance (solvents, non-oxidized bases, acids and oils) and heat tolerance up to 120–138 °C in the fiber-filled grades, and it becomes a practical choice for lightweight airframe and structural UAV components, brackets, housings and payload fixtures that fly outdoors and take chemical exposure.
For defense and NDAA-scope UAS programs, PP is made in-house by Prusa and supported through a single US-based team. Tell us about the airframe and mission environment and we’ll help you spec it.
Made to print together
Both fiber-filled grades need the PP print sheet (or a separation layer) and a hardened nozzle. Print in a well-ventilated space; an enclosure helps contain odor and can improve layer adhesion.
